Reports assignment to, or modification of lambda parameters.
Although occasionally intended, this construct may be confusing and is often caused by a typo or use of a wrong variable.
<p>The quick-fix adds a declaration of a new variable.</p>
<p><b>Example:</b></p>
<pre><code>
  list.forEach(s -> {
    s = s.trim();
    System.out.println("String: " + s);
  });
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
  list.forEach(s -> {
    String trimmed = s.trim();
    System.out.println("String: " + trimmed);
  });
</code></pre>
<!-- tooltip end -->
<p>Use the <b>Ignore if assignment is a transformation of the original parameter</b> option to ignore assignments that modify the parameter
  value based on its previous value.</p>
